With the development of the routing industry, the market demand is more extensive, but many users still do not understand the routing configuration issues. Here we mainly provide a comprehensive description of the Cisco router NAT configuration. More and more INTERNET resource sharing methods are available. In most cases, ddnleased lines are widely used with their stable performance and good scalability.

Recently, a friend asked me how to configure static NAT for a Cisco router to allow Internet users to access the Intranet Web and email servers through a Cisco router. Obviously, this function requires NAT between the public IP address and the Intranet IP address. The following are the specific implementation methods.
The market demand for Cisco routers has been very high. Here we mainly analyze the detailed knowledge of Cisco router configuration and RJ45 console connection, for accessing and configuring I0S on a new router, we must communicate with the Console port.
After connecting a console terminal with the Console port configu
It is very important to know some common knowledge about CISCO routers. Here we mainly explain the CISCO router tutorial, which provides a detailed analysis from configuration to access methods. This document uses Cisco2620 as an example to describe how to configure the vro and remote access, this article discusses how to use the DHCP service function of the inte
Recently changed jobs, the company more than 40 people share a 20M bandwidth wireless network, the router for Cisco R2911. Boss, let me make a cacti to monitor Cisco routed network card traffic.

Cisco router configuration mode
In general, you can configure your router in 5 ways:
1.Console Port connection terminal or running terminal simulation software of the microcomputer;
2.AUX Port Connect modem, connect with remote terminal or computer running terminal simulation software by telephone line;
3. Via the TFTP server on the Ethernet;
4. Adoption of
For enterprise users, multi-device port access control can optimize the network more reasonably. Here we analyze in detail how to configure a Cisco router to implement this function. You only need a CISCO router with an asynchronous module or a router with a built-in asynchr
The importance of vro configuration is self-evident. Here we mainly analyze the Cisco router configuration statements in detail, and share them with you here, hoping to help you.

China Mobile's GPRS network uses the APN method to connect to the GPRS device terminal and communicate with the server through the APN. The customer purchased the Cisco 2811 router, and the mobile company needed to pull the optical fiber through the E1 port, I spent more than 1000 RMB with an E1 module. mobile companies are doing very poorly, and optical fiber connectors are not provided at all. I also boug
For Cisco router authentication, when performing the cisco Route Selection protocol (r12002; VPN) authentication, the key is irrelevant to the key ID when using plain text (General authentication, during MD5 authentication, the key and key ID are related, that is, the key IDs and keys at both ends must be the same, for example, R1 (config) # key chain key1 R1 (co
For many beginners, using cisco rommon to maintain a vro, the ROM Monitor of a cisco router is often unfamiliar or even daunting. The reason is simple. First, we do not often use this mode, I am not familiar with the related operations. Second, Operation errors in ROM Monitor mode often cause fatal damage to the vro (such as destroying the IOS file in flash, lead
The command line port of a cisco router uses a hierarchical structure, which requires logging on to different modes to complete detailed configuration tasks. From a security perspective, cisco IOS divides EXEC sessions into USER mode and privileged mode.
Features of the USER mode:
In USER mode, only basic monitoring commands are allowed. In this mode, the confi
